METHOD OF STIFFENING PILE FABRICS- To all whom it may concern.-

Be it known that I, FREDERIG E. KIP, a citizen of the United clair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Methods of Stiffening Pile Fabrics, of which the following is a specification.

T/Vhen pile fabrics, such as velvets and plushes, are woven, they are supple and flexible, and in order to stiffen them it has been the practice to apply to the back of the fabric while it is stretched a stiffening substance, then dry it, and then smooth it with a hot iron applied to the' back. By this method, however, it is found to be difficult, if not impossible, to apply a sufficient quantity of the stiffening or colloidal solution, because of the danger of said solution passing through the back of the goods and injuring the pile on the face thereof, as the stiffening solution may not be very thick or viscid when applied. In carrying out the process in the old way it has been the practice also to apply the heat for drying the stiffening solution to the face or pile side of the fabric.

The present process or method of stiffening pile fabrics has for its object to apply more than the usual quantity of the stifiening solution to the back of the fabric without risk of its going through and injuring the pile on the face and to effect ing by applying the heat directly to the back of the fabric. By applying the heat directly to the coated surface and without passing through the pile side of the fabric the coated surface is dried quicker and the silkiness of the pile imparted by previous finishing esses is retained.

In carrying out the invention a thick stiff ening solution is first the fabric in a thin film, and this film is then dried thereon. A thinner solution of the same material is then applied in greater quantity to the already-coated surface and this second coating is dried. The surface is then smoothed or polished with hot irons. The drying of the coats of stiffening material is effected by radiant heat applied directly to the back of the goods which is coated with the stiffening material.

The accompanying drawings illustrate an apparatus or machine by which the method may be carried out.

remainder or continuation of the same, the machine being, in practice, quite long.

A is a long supportingdrame in which are mounted two pairs of long endless chains B and B, forming carriers, mounted on sprocket-wheels C, driven at a uniform rate of speed by any suitable means. The chains carry pins which engage the selvages of the fabric and keep it stretched widthwise.

Over the chain carrier B is a heater D, consisting of a metal plate situated just above the level of the fabric and gas-jets for heating said plate, and above the chain carrier B is a similar heater D.

E represents the pile fabric to be treated. The strip of fabric 0 is led over suitable rollers and tension devices to the first point X, where the stiffening material x is applied to the back of the fabric, which is uppermost. The surplus material is scraped off by a scraper a, and the fabric is carried by the first chain carrier B under the heater D, where the coat ing of stiffening material is dried. The fabric now passes the second point X, where it receives the thinner stifiening material or, the surplus material being removed by a scraper a. The strip of fabric now passes to the second chain carrier B and is carried by it under the heater D. This heater dries the second coating of stiffening material. The fabric as it moves along is now polished or amore thorough dryl ironed with hot irons, either by hand or otherwise, and the finished fabric is led over a steam-drum F and rack G.

The mechanism shown is not herein claimed, being embodied in another pending proc I application, Serial N 0. 45,280, filed January 30, 1901, and this invention is not restricted to any special mechanism or apparatus for carrying it out.

It should be noted that the stiffening material or solution (which is itself known in the art) is quite thick at the point X, where it is applied directly on the fabric, and there is no liability, therefore, of its penetrating to the lower or pile face of the fabric. After this coating is dried on the fabric the second coating, at X, may be applied in a thinner condition and in any quantity desirable without danger of penetration, as the first coating protects the fabric. By this means a much better and fuller coating of the stiffening material may be applied than heretofore and a more glossy and finished effect produced by the ironing.
